F(x) = 3(x-4)^2-38 because finding the perfect square would get you f(x)+38=3(x^2-8x+16) and then finding the squareroot of that and moving the constant on the left back to the right would leave u with f(x)=3(x-4)^2-38
She used the associative property which should only be used with positive numbers (sorry if it isn't the answer you're looking for)
Multiply the amount with the discount
95 x 0.15 = 14.25
Since it is discount, subtract $14.25 from the total amount: $95
95 - 14.25 = $80.75
B) $80.75 is your answer
hope this helps
